2002 AMERICAN IRON HO TEJAS SJ loose transmission splines

Apr 12, 2013 • I have a 2002 AMERICAN IRON HO TEJAS SJ in my shop right now. I am trying to locate a couple parts and am having some difficulty locating them since there is no parts diagram like other makes and models have that I can find...Show more

I have looked several places including the parts cross reference sheet located at American Ironhorse Owners Organization. But haven't found what I am looking for. I would appreciate any help or advice you can give

1) I need a front brake master cylinder diaphragm

2) I am looking for some information on the clutch basket -
(This bike had the clutch plate rattle sound that is familiar with open belt type drives (I was unaware of this being considered normal until I found the clutch plates were making the noise and did a little online research)

When I removed the transmission input drive there was a lot of what I would say was shellac on the splines of the trans input shaft as well as the clutch basket. I cleaned all that up and put the basket back on to check the trans input bearing for play I found the splines are loose even with the left handed nut tightened. There is no visible damage or wear on either of the splines that I can see. I also don't feel any sharpness on them which would also indicate wear. There is damage to the inside cover from the basket rubbing on it. But that damage does not appear to have been caused by this assembly as there is no wear or damaged to the flywheel or clutch basket. I suspect this clutch basket has been replaced and the wrong part installed, possibly the shellac (or gasket maker) was added to sure up the play...

I managed to locate a number on the transmission -

"JIMS" is cast on the top (Thanks to "CopperSled" from the "V2-forum dot com" for pointing out it was, "JIMS and not HMS" like I thought)

The number on R/S bottom of transmission is JM1K4797

UPDATE:

I called JIMS Transmission at (805) 482-6913 - Lady said it should take a "90 to 99 Softail Evo style clutch". She said JIMS made/sold 5 speed transmissions to/for American Ironhorse up to 2003 and after that they were 6 speed transmissions, If I understood her correctly. (And I'm not good at information retention, BTW) ....

I called our local Harley dealer, he said he didn't know anything about the American Ironhorse bikes. But using the information JIMS gave me... a 90 to 97 Harley Evo "clutch Hub" Harley Davidson PN. 37550-90A for $147.12 should fit. It's "not in stock" so I can't go get it and try it out on the shaft to make sure it is the correct fitment or fits tighter than what I have here in front of me.

Also the Harley dealer said that PN. 37550-90A was for 90-97 Harley's - 98 up was a different number so there is a little conflict with JIMS. But I am getting closer, at least I have a dollar amount and a part number...
